Abstract
As a development of our previous work, we performed a kinetic study of the oxidative cyclization reaction of some 2,4-diaryl-substituted aldehyde thio semicarbazones 1a-n induced by ferric chloride and by cupric perchlorate. T he results of cyclization of 1a-n were compared to those of the correspondi ng 2-methyl derivatives. The kinetic data were analyzed by means of the Ham mett's equation.
